I am trying to eliminate my file extension .php and add a / to open it for forward url stacking. With of course keeping infinite loops on mind. This is what I have in htaccess file. What am I doing wrong?

<IfModule mod_rewrite.c>
   RewriteCond %{HTTPS} !=on
   RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
   RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]   

 </IfModule>
 
# Removes index.php from ExpressionEngine URLs 
 <IfModule mod_rewrite.c>
        RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /index.php/$1 [L]
		
</IfModule>

Thank you
